Real elastic materials stay purely elastic only up to what deformation?
AAny deformation at all
BDeformations at speed
CVery small deformations
DDeformations twice the length
Answer & Solution
Correct answer: C. Very small deformations
Perfect elasticity is an ideal concept; in practice permanent plastic deformation sets in after small deformations.
